A memory allocation problem in file was found by Jeff Johnson, and a stack overflow corruption problem was found by David Endler. These problems have been corrected in file version 3.41 and likely affect all previous version. These problems pose a security threat as they can be used to execute arbitrary code by an attacker under the privileges of another user. Note that the attacker must first somehow convince the target user to execute file against a specially crafted file that triggers the buffer overflow in file.
